DECEPTION – In So Many Ways –
Feb. 26, 2026 – Costco is falsely claiming its store-brand tequila as being made with 100% blue agave. However, tests showed that the tequila varieties actually contain high levels of non-agave alcohol. If it’s true, it means that the tequila is being marketed as higher quality than it actually is…customers are being deceived into paying a higher amount for it. According to tests ordered by the plaintiff, Kirkland Signature Blanco Tequila — which is labeled as “100% de Agave” — contained up to 40% non-agave alcohol. Only Mexico can legally make tequila, and Mexican laws are strict about regulating the alcohol. To be considered tequila, a beverage is required to be made from at least 51% blue agave. Anything that contains 100% agave is considered to be premium, meaning it should command a higher price tag than “mixto” tequila varieties, as they are called.
